Philadelphia’s network infrastructure is messy, clumsy, and often unseen by the general public. Wandering the streets, you may get a vague understanding of what’s going on—a manhole cover sits unassumingly on the crosswalk, or maybe a mysterious box with an antenna sits high upon a wall in a back alley, humming into the night. Under your feet and above your eye line, data is soaring by through brightly-lit fiber cable and ethereal radio transmission. The city is alive, but few may ever understand to what extent.
